Functional analysis and treatment of problem behavior evoked by noise.

The team worked with two children who had developmental delays. Both kids hit, screamed, or threw things when they heard everyday noises like vacuum cleaners or hand dryers.

First the researchers ran a short functional analysis. They played noise for a few seconds. If the child asked for a break or covered their ears, the noise stopped right away. Problem behavior jumped only in this noise condition, so the team knew noise was the real trigger.

After the test, treatment took 5–10 sessions. The adults no longer let the kids escape when noise played. They also started the sound very soft and slowly made it louder while the children stayed at the table.

Both children’s problem behavior dropped to near zero. Parents later said the gains held at home and were still strong weeks later.

Lowe et al. (1974) showed that rats will work to turn off loud noise only if the noise was first paired with shock. Meuret et al. (2001) now show that noise alone can evoke problem behavior in children without any shock history. The two studies line up: once noise is proven aversive through a functional analysis, escape extinction works for both species.

Newman et al. (2021) tried non-contingent snacks instead of escape extinction for escape-maintained behavior. Some kids improved, others did not. Meuret et al. (2001) add clear evidence that when noise is the trigger, blocking escape plus fading the volume is a reliable choice.

If a client melts down around vacuums, blenders, or school bells, run a 5-minute noise test before writing a behavior plan. When the functional analysis shows noise is the culprit, stop letting the child leave the area. Start the sound barely audible and raise it bit by bit while the child uses headphones, tasks, or DRO. This pairing cuts problem behavior and travels home with them.
